You will have to convert those IP addresses to actual numbers (each
dot represents a power of 256) and then sort the data by start address
to enable you to determine the ranges correctly. Then you would be
able to find the nearest (lower or equal) start address using VLOOKUP,
and then check the end address to see that it is not lower than your
sought address.

Hope this helps.

Here you can find an Excel VLOOKUP function that works on a list of subnets.
